The Sealed Book is a forbidden book sealed by the First Hokage Senju Hashirama, and exists in the form of a scroll.

The book records many ninjutsu that were learned or created by the previous Hokage, but were sealed because they were too dangerous.

For example, the art of multiple shadow clones.

The shadow clone technique is not a forbidden technique. It can divide one's own chakra into equal parts and create a physical clone.

This clone can master knowledge, fight, and has independent consciousness. But the clone knows that it is a clone and can unlock ninjutsu on its own.

Once the ninjutsu is released, the clone disappears. The knowledge, experience, and things the clone has learned will be immediately transferred to the main body and other clones.

The reason why the art of multiple shadow clones became a forbidden art is also because of the point of "equally dividing one's own chakra".

Chakra is a kind of energy extracted from a mixture of spirit and cells. The chakra of ordinary ninjas is extremely limited.

Assuming that the limit is one hundred, the chakra required to perform the shadow clone technique is 30. Then, after using the multiple shadow clone technique, the amount of chakra of each clone will become 100 - the number of clones x 30, and then divided by

The total number of clones.

In other words, if an ordinary ninja splits three shadow clones, he will reach the limit. With four shadow clones, the chakra in the body will become negative, draining himself dry, causing serious injury or even death.

Moreover, after the shadow clone disappears, not only the knowledge and experience, but also the fatigue and pain of the shadow clone will be transmitted.

Every time Naruto used the Multiple Shadow Clone Technique to summon thousands of shadow clones, and these shadow clones were destroyed, it was equivalent to him suffering thousands of times in a short period of time.

Therefore, Uzumaki Naruto's willpower is the best in the world!

Another example is the art of reincarnation. Using a living body to carry the soul of the dead and summoning immortal monsters is contrary to human ethics. Just thinking about it makes people feel terrible.

What’s interesting is that most of the ninjutsu in the Book of Sealings can be traced back to their origins and are related to the Second Hokage, enough to be called the ‘Forbidden Jutsu Madman’.

The attraction of powerful ninjutsu to ninjas is undoubted.

After Su Yue made this suggestion, many special jonins from small families made some changes.

Some of their ninjutsu have the characteristics of their own family, but they can't be said to be very strong. Otherwise, they wouldn't be particularly jounin.

These special jounin thought that if they could trade their family ninjutsu for the ninjutsu in the Book of Sealing, they might be able to take off their 'special' hat and become a real jounin.

Among these family ninjas, Kakashi is also thinking.

Known as the 'copy ninja', if he is serious about it, he can produce a considerable number of ninjutsu, and even the Hatake family swordsmanship.

But Kakashi was extremely disappointed with the Third Hokage.

The death of his father, the death of his teacher, the death of his teammates, the family members of his teammates were wiped out, the teacher’s son was abused since he was a child...

Each of these events, as well as his previous ANBU career, were slowly changing his attitude towards the Third Hokage.

From admiration at the beginning, to doubt later, to disappointment at the end.

Otherwise, he would not have stopped Kai from rescuing the Third Hokage when Orochimaru was carrying out the 'Konoha Collapse Plan'.

Because if Kai works hard, he can definitely save the Third Hokage.

But Kakashi didn't want his few friends left to fight for the Third Hokage.

So, he just stood there quietly without speaking.

In the field, after the Uchiha family was wiped out, as the largest family in Konoha, the leader of the Hyuga clan, Hinata Hibiscus, received the attention second only to the Third Hokage.

Speaking of secret techniques, the Hyuga family’s Rou Fist is well deserved.

But this move is closely related to the Hyuga family's blood lineage and Byakugan.

It's not like the Hyuga clan has never taught others the soft fist. But without Byakugan, the power of the soft fist is much inferior to that of the steel fist.

But Rou Fist is the specialty skill of the Hyuga clan, and he cannot just hand it over to let others understand the weakness of Rou Fist and find ways to restrain it.

Therefore, facing Su Yue's gaze, he looked calm and said respectfully.

"The Hinata family will provide some chakra meridian research charts that can only be seen by the Byakugan. I hope it will be helpful to the 'medical department' established by the Hokage-sama."

He avoided the important part, skipped the part about combat, and focused on the medical department.

After handing over a unique secret that only Byakugan can draw and study, no one else can pick on the Hinata family.

The ninja clan, headed by the Hyuga family and Ino Shikacho, who was close to the Hokage, also responded happily.

The Nara family contributed the prescription, the Yamanaka family provided some research on genjutsu, and the Akimichi family provided a special soldier's grain pill, which is three times more effective in replenishing energy than other soldiers' grain pills.

With them as an example, other ninja families also provided some ninjutsu, which immediately expanded the ninjutsu reserve of Konoha Village.

Su Yue did not break his promise. For each family that contributed ninjutsu, he provided one or two forbidden techniques from the Book of Sealings based on their shortcomings.

Although the practice of these forbidden techniques is not easy, the vast majority of family ninjas are satisfied - forbidden techniques can also be passed down from family to family!

Besides, although they contributed some ninjutsu, it does not mean that they cannot continue to teach these ninjutsu to their children!

…

This meeting started at dawn and lasted until the end of the moon.

After all the Jonin left, Mito Menyan finally couldn't help but said to Su Yue.

"Sarutobi. Why didn't you discuss such a big matter with us before bringing it up? Whether it's about letting ninja families, big or small, provide ninjutsu, or about establishing a ninja high school, if anything goes wrong, it's a big deal for Konoha.

A huge blow!”

"As long as I am alive, Konoha will not fall."

Su Yue knocked on the cigarette rod in his hand, and his whole appearance slowly changed.

His gray hair turned black, and his thin body gradually became fuller, filled with strong muscles.

Even his stature, which has shrunk due to aging, is getting taller.

Soon, Su Yue, who had returned to his peak appearance at the age of thirty, looked coldly at the two advisor elders who were extremely surprised.

"Unlike you, I have already abandoned my training! Tsunade has already developed the Yin Seal Technique, why can't I learn it?"

Thirty years have passed. Looking at Su Yue's majestic momentum and sharp edge, the two consultant elders seemed to have traveled through time and suddenly fell into silence.

They were still wondering why Danzo was killed by Hiruzen Sarutobi without any sound.

Even though he is old, Sarutobi Hiruzen is no longer young!

But now, they finally know why.

Looking at Hiruzen Sarutobi who seemed to have snatched back thirty years of time from fate, Mito Kadoen's voice was dry.

"When did you learn the Yin Sealing Technique?"

"Does it matter?."

Su Yue asked back.

"Indeed, it's not important."

Mito Kadoyan sighed deeply and left with Koharu who went to bed.

The two of them knew that from today on, Sarutobi would no longer be the 'weak and easy-to-negotiate' third-generation Hokage before.
